it is an object of my invention to, provide an improved ,sinker for amachine of the kind described for knitting loop-plush fabric. To thisend, I arrange the usual set of needles, and sinker allotted to eachneedle with a nib directed toward the front side of the allotted, eedle,i. e., that addition to the plush throat, a web-holding edge or step isformed in the upper, edge of the nib .which is at a higher level thanthe, plush throat. In order toprevent interference with the free 5movement offtheplush loop of! the point of nib, the section of the nibis so determined by suitable arrangement of the upper and lower edges ofr the nib that it is a maximumat the rear end side of the needle wherethe latchls provided, and or root of the nib, as will be described.

It is still another object of my invention to provide an improvedknitting, machine for operat- 2o ing the sinkers according to myinvention. To this end, I provide a lock with an upper and a lower camfor cooperationwith the butts of the sinkers, ,and means for activeposition withrespect to the sinkers. The individual-sinkers are equippedwith butts for cooperation with one or the other cam, so that my machinerequires two kinds of sinkers, one

The ground-thread throat need not bein exactly vertical position below the plush throat but is preferablyarranged ahead of theplush throat. In a sinker oi this type, the lowerend of the throat for the plush thread is ata lower level than the pointof the nib which in turn is positioned at a higher level than the throatfor the ground thread, and this arrangement, renders for separating theplush and ground threads when the sinker ground-thread above its lowerend is verticaior substantially vertical and preferably inclinedto therear,and

Figs. '18 to 21 are diagrams illustrating sinkers of the kind shown inFigs. 1, 2 and 3, equipped with means for obtaining fabrics of variousde-i grees of closeness. I

Referring now to the drawings, and first to Figs. 1, 2 and 3, themachine is equipped with a lock having two cams for cooperation with itsknocking-over sinkers, as will be described, and therefore it requiressinkers of two kinds for cooperation with the individual cams of thelock. s are the sinkers forcooperation with the lower, and s" are thesinkers for cooperation with the upper cam.

Referring now to Figs. 2 and 3, both kinds of sinkers, s and s", arenotched at i8 for the reception of a cam ring, as will alsobe described.The rear ends 31 of both kinds are vertical, and in the sinkers s, forcooperation with the lower cam of the lock, the lower edge of the butt33is flush with the lower edge of the sinker,-while in the sinkers s, forcooperation with the upper cam, the butt 34 is placed at'a higher level.

The beaks of both kinds of sinkers are similar and will now be describedwith reference to Fig. 1 for a sinker s which may be designed forcooperation with the lower or upper cam of the lock at its rear end. 2is a nib above the notch 3 at whose rear end is the ground-thread orcastingofi throat 9, and whose lower edge is the web- 'I'he pointed end5 of the nib 2 is at a higher level than the lower end 4 of the plushthroat 1 for the plush-loop thread 21. The upper edge 6 of the nib 2extends in downward direction from the point 5 toward the lower end 4 ofthe plush throat 1 in an unbroken curve but may be stepped as willbe'described with reference to Figure 4. The gradient of the edge 6toward the end 4 facilitates the introduction of the plush thread 27from above. However, the plush throat may be inclined in forwarddirection, as will also be described with reference to Fig. 4. The loweredge 8 of the nib 2 is an unbroken curve, like its upper edge 6,-andextends from the point 5 of the nib 2 down to the upper end 8 of thegroundthread throat 9 where the ground thread 28 is placed. Theground-thread throat 9 is positioned substantially vertically below thelower end 4 of the plush throat I. Substantially vertically means thatthe ground-thread throat need not be exactly vertically below the lowerend 4 of the plush throat, and preferably it is slightly ahead thereof,as shown.

A modified sinker will now reference to Fig. 4. is arranged above thenotch 3 as described but its upper and lower edges 5 and 8 arenotunbroken curves, as shown in Figs. 1 to 3, but the upper edge 8 has asubstantially horizontal step end 4 of the plush throat be describedwith and a-gradient 55 connecting the horizontal portion 55 to the lowerend 4. The plush throat 55 forward direction and the upper end of theground-thread throat 9 is arranged at a by the upper cam 5|.

' ject, respectively, The nib 2, with its point 5,

considerable distancei'orwardly of the lower end 4 of the plush throat55. The lower edge 801' the nib has a gradient which is substantiallyparallel to the gradient 55 of the upper edge. The two stages at 55 andat 4 permit the sinking of plush loops of various lengths. The conditionwhich is to be fulfilled in order that no tension is exerted on a loopwhich has been sunk at the lowest point 4 of the upper edge 6, when itslides on the step 55 which is at a higher level than the point 4, isthat the cross-sections of the nib should decrease from 4 toward itspoint 5, or, in

other words, that the cross-section at the root the distance a betweenthe throats 4 and 8 must be equal to the vertical distance b of throat 4from the web-holding edge of notch 3.

Fig. 5 shows a complete sinker of the type illustrated-in Fig. 4, forcooperation with the lower cam of the look. A sinker for the upper camhas not been illustrated, it being understood that the only distinctionof this sinker is the position of its butt at 34.

Referring now to'Figs. 6 to 9, these illustrate a portion of a circularknitting machine, only those parts having been illustrated, which mustbe shown in order to enable a person skilled in the art to understand myinvention. Thus, the sinker camming portions, such for engaging in theslots 3! of the sinkers.

25 and 5| are, respectively, the lower and upper cams, already referredto, of the lock. In the present instance, only sinkers s forcooperationwith the lower cam 25 have been shown in the machine, and so the uppercam 5| is idle and only the sinkers s, with their butts 33, are operatedby the lower cam 25 for forming plush loops as will be described.Similarly, only sinkers s might be inserted and their butts 34 beoperated As a rule, sinkers s and s" the'upper cam 5|, into activeposition. Both kinds'of sinkers, s and s", may also be operated at thesame time by a third cam, not shown, if required for a given pattern.

The cam 25 has camming portions, such as 25 and 25 for engaging thebutts 33 of the sinkers Both cams are mounted in suitable guides,notshown, and placed one upon the other for free relative displacement.Lugs 25 and 5| profrom the outer ends of the cams 25 and 5| at. oppositesides thereof. A slide 53, with a pairof camming faces I53 and I54 atits upper end, is mounted to slide in the frame of the machine forcooperation with the lug 5| of cam SI, and a similar slide 52, with asingle camming face at its upper end, is mounted for cooperation withthe lug 25 of cam 25. Two springs I55 are provided for pulling the lug5! of cam 5| against its slide 53, and similar springs I 56 are providedfor pulling the lug 25 of cam and 12, Fig. 11 showing only 25 againstthe slide 52. The free ends of the springs are attached to a suitablebracket I51.

Any suitable'means may beused foroperating the slides 52 and 53. Intheexample illustrated, fork-shaped rocking levers I58 fulcrurned at I59areprovided for this purpose, and. operated by connecting rods I60 fromany suitable mechanism, not shown. The free endsof the rocking leversI58 bear against the lower endsof theslides 52 and 53, and springs I5Iare attached to arms. I52 on the slides atone end, and to the bearingsI59 of levers I58 at the other end. In the position illustrated in Figs.6 and8, the slide 52 hasbeen raised by its lever I58, and its cam facehas pushed the lower cam25 inwardly for cooperation with sinkers s. 1 I

Certain sinkers and needles have been selected for describing theircooperation with each other and with the lower cam. 25 which has beenmoved into active position by slide 52, and these sinkers and needleshave been marked with reference numerals, as indicatedat the. left inFig. 6. The section line VIII-.-VIII in Fig. 6 extends through thesinker s (3IJ3) which is between the needles n(II) and n(I2 As theneedles and sinkers rotate about the axis a: in the direction of arrowA, while the cam 25 and the cam ring H are stationary, the sinker s(303) is just going to run off the camming portion 25 --25 of cam 25 atthe end 25 and torun, onto the subsequent camming portion. The cammingring 311, does not influence the sinker s (3Il3) as itswidth at thecamrning portion 3I'I is less than the width of the slot I8 in thesinker.

Referring to Fig. '7. theneedleni3ll9) which is the first one inthedirection of arrowA, is in its The subsequent needles are lowered intotheir lowermost positions, 11.( I4) and n(I5), and then raised again,beginning with 11(I5 The plush-loop thread 21- and the ground thread 28which issue from the thre fi uides 29 and 30, respectively, are so .farapartat the point where the sinker-s (,2) is positioned, thatthe point 5at the end of its nib 2 entersbetweenthethreads, as shown in Fig. 10.The nib which is directed toward the front or latch side of theneedle,and in the position illustrated in Fig. 10 has moved beyond theback of the needle with its point 5, holds the plush-loop thread hook ofneedle n(IIl), separate from the ground thread 28 which is in theground-thread throat 3.

The needle descends while the sinker s (2) moves toward the left, asindicated by the arrow B. The plush-loop thread 21 isguided toward thelower end 4 of the plush throat I by the upper edge 6 of the nib .2.

An intermediate position is shown in Figs. 11

of the sinker s (4) and the needle n(I2), drawn to a larger scale thanFig. 12. Here, the plush-,- loop thread 21 is at the lowerend 4 of theplush throat .I, and the ground thread 28 is at theupper end 8 oftheground-thread throat 9. The latch of the needle has been closed and theback i of the needle shank engagesthe groundthread 28 in the throat 8.Fig. 12 shows the same operation. The needle still descends and thesinker still movesin the direction of arrow B,toward the left. a 1 Figs.13 and 14 show the sinking operation," in a manner similar to theshowing of Figs. ll and I 12, for theneedlen(l4) and the sinker 8 (6).

This configuration preventsthe plush loop 56 from sliding upwards on the edge, and becoming slack.

The ground thread 28 is caught between the shank of the needle n and thethroat 9, as best seen in Figs. 11 and 13, so that the ground thread 28.is locked against horizontal movement, like in its throat 4, and, in

the sinking position, Fig. 13, the ground thread 28 is in front of theplush-loop thread 21. It does not move from this position until thesinking movement has been finished, and consequently also during thesubsequent casting-off movement. With a sinkeraccording to my invention,the plating of plush goods is effected under absolutelyreliableconditions, and this was impracticable. heretofore, because the groundthread 28 had a certain freedom of movement in the space between theshank and the latch of the needle so that frequently the ground thread28 swings in horizontal. direction,and. before sinking, is placed at therear of the, already sunk, plushloop thread 21, instead of being infront of such thread.

cause the sinker moves in direction D. The loop becomes slackerandslacker while ascending the edge of the nib, and finally slides off, thenib 5 unobstructed, when the sinker has moved far enough to the rear. InFig. 1'7, the point 5 of the nib is just about to be extracted from theloop 55.

If the ground-thread throat 9 is at 9a, as shown in dotted linesin Fig.4, and the distances a and b are equal, as described, a being the lengthof the plush loop 55, the tension of the loop 56 is equal to the tensionof the ground thread.

If the upper edge 6 is stepped. as also shown in Fig. 4, in order toobtain plush loops 56 of various art) the vertical crosssection of thenib 2 at the lowermost step 4 must be the largest cross-section of thenib,

along the upper edge 6 of nib 2 and the step 55 It will appear from Fig.4 that the vertical sec to 5 are such that the 8 decreases from 4 to 5.

I A plush-loop throat 55 which is inclined in forward direction, asshown may be preferable to the rearwardly inclined throat I, as by itthe thread is positively placed below the nib, the operation ofcasting-off is performed reliably, and

the plated goods obtained areof good quality.

Sinkersaccording to my invention may be de signed forivarying thecloseness of the fabric which is knitted on a circular machine.

It is in circular knitting machines of the usual type, it is imknown Ithat equipped with sinkers 1 possible to knit a given portion of acourse .of

loops more closely or more loosely than its other portion. This drawbackis particularly difficult if it is desired to knit certain courseswith,.and other courses without, plush loops. For instance,,assume thatin a two-threaded fabric the second thread is knitted into plush loopsfor splicing certain. portions of the fabric, for instance, the sole ofa stocking, without knitting an extra splicing thread into this portion,the plush-looped portion of the fabric becomes stronger but at the sameime the structure of its ground-thread loops becomes more loose than in.a two-threaded plain'fabric, without plushloops, and the plush becomestoo thin. Therefore, in order to impart to the fabric, and particularlyto its plush-looped portion, the required strength, the machine must beadjusted for closer knitting, but this involves the drawback that, ifthe ground-thread structure of the plush-looped portion is close enough,the'portIonwithout plush loops becomes too close. If a thinner thread isused for the plush-looped portion than for the plain portion without theplush loops, the plush-looped portion must be knitted more closely stillthan would be required if, as

' assumed above, the threads for both portions are of equal thickness.In such cases, the drawbacks of existing circular knitting machines areparticularly apparent.

Conversely, it may occur that a single thread, or several threads, areused for the plush loops which thread, or threads, is so thick that theground fabric in the plush-looped portion must be knitted more looselythan the plain portion without the plush loops, in order that thesplicing by the plush loops does not become too hard, and the too tautknitting does not cause undesirable consequences during the formation ofthe loops. This operation is also impracticable in existing circularknitting machines, and particularly, it cannot be performed if only aportion of the courses is tobe knitted with plush loops.

It is another object of my invention to eliminate the aforesaiddrawbacks. The problem is, in fabrics knitted on circular knittingmachines, to knit more closely or more loosely, as may be required, theground fabric of the portion which has plush loops, than the plainportion without the plush loops, in such manner that the length of theplush loops is the same for the more closely and for the more looselyknitted ground fabric of the plush-looped portion. .I solve this problemby sinking the loops of the ground fabrlc for the plush-looped portionshorter than for the plain fabric, if the structure of the ground fabricfor the plush-looped portion is to be closer than for the plain portionwithout the plush loops; and by sinking the loops of the ground fabricfor the plush-looped portion longer than for the plain fabric, if thestructure of the ground fabric for the plush-looped portion is to belooser than for the plain portion without the plush loops.

In order to obtain uniform length of the plush loops in both cases, theposition of the plushloop throat I is the same as to its'level withrespect to the needles, while the position of the ground-thread throat8* plush-loop throat I is varied as required for closer or looserknitting of the plush-looped portion than the plain portion without theplush loops, the ground-thread throat being positioned at a higher levelfor longer, and at a lower level for shorter, ground-thread loops in theplush h ned P rtion with respect to the- I suggest to solve this problemby providing sinkers in which the web-holding edge for the ground threadis arranged at two distinct levels, the front portion being arranged atthe normal level with respect to the hooks of the needles ,for sinkingnormal plain fabric, at normal closeness, while below the plush throat Iwhere the plush loops are sunk, the web-holding edge is arranged at alevel above or below its front poroperation with the upper cam 5| aswell, serves for knitting the ground fabric more loosely for theplush-looped portions than for the plain portions, and therefore itsground-thread throat I64 is arranged at a, higher level than the frontportion I65 of the web-holding edge.

It is known that for knitting fabric with plush loops the sinkers areadvanced earlier and for a longer distance with respect to the needles1!. than for knitting plain fabric. Fig. 18 shows the position of thesinker in which plush loops are knitted. In this position, the pointwhere the ground thread 28 is sunk by the needle n, is just below theplush throat 4. At this point, the web-holding edge is raised to formthe ground-thread throat I64 at a higher level than the front portionI65. 7

Fig. 19 shows the position of the sinker for knitting plain fabric,without plush loops. For this operation'the sinker remains in itsinitial position, and-the point where the needle 12 sinks the groundthread, is now on the web-holding edge, at some distance to the rearfrom its front portion I65, where a depression or step is provided atI66. The loops of the ground thread 28 are longer in Fig. 18 than inFig. 19.

Figs. 20 and 21 show the same positions of the sinker as in Figs. 18 and19, but for knitting a fabric whose ground fabric is knitted moreclosely in the portions having plush loops, than in the plain portions.In this sinker, the ground-thread throat I61 is arranged at a lowerlevel than the front portion I65 of the web-holding edge. The loops ofthe ground thread 28 are shorter in Fig. 20 than in Fig. 21.

It is not necessary to adjust the machine for closer or looser knittingwhile knitting a course, all that is required being to use sinkers witha high-level ground-thread throat I64 for a loose ground fabric in theplush-looped portions, and.

with the ground-thread throat I64 or I61 at a lower or higher level thanthe -of the web-holding edge.
